JGraph is a member of the fastest growing breed of software products:
professional open source software. JGraph is able to combine the best of each
open source software and traditional software development to form a uniquely
powerful offering.

JGraph
: The free Swing-style component with
source code, 140k in size, feature-rich, fully documented and commercially
supported.

JGraph Layout Pro
: Powerful and fast graph
layouts provide automatic positioning functionality to improve user's visual
experience.

JGraphpad Pro
: Complete rich-client
platform for rapid application development. For graph applications where
time-to-market is critical.
JGraph is the most powerful, easy-to-use, feature-rich and
standards-compliant open source graph component available for Java.

Welcome to JGraphT - a free Java Graph LibraryAbout JGraphT
JGraphT is a free Java graph library that provides mathematical graph-theory
objects and algorithms. JGraphT supports various types of graphs including:

• directed and undirected graphs.
  
• graphs with weighted / unweighted / labeled or any
  user-defined edges.
  
• various edge multiplicity options, including: simple-graphs,
  multigraphs, pseudographs.
  
• unmodifiable graphs - allow modules to provide "read-only" access to
  internal graphs.
  
• listenable graphs - allow external listeners to track modification
  events.
  
• subgraphs graphs that are auto-updating subgraph views on other
  graphs.
  
• all compositions of above graphs.

Although powerful, JGraphT is designed to be simple and
type-safe (via Java 5 generics). For example, graph vertices can be of
any objects. You can create graphs based on: Strings, URLs, XML documents, etc;
you can even create graphs of graphs! This
code example
shows how.
Other features offered by JGraphT:

• graph visualization using the JGraph library (
  try this demo!
  )
  
• complete source code included, under the terms of the
  GNU Lesser General Public License
  .
  
• comprehensive
  Javadocs
  .
  
• easy extensibility.
